Momoka Sasaki, often referred to by the nickname Moka, is a supporting character in the slice-of-life story centered on three young girls. She is the older sister of Nonoka Sasaki and belongs to a family that runs a bakery called Sasaki Bread in the Ueno district of Tokyo. Momoka is presented as a young adult who is warm-hearted, dependable, and exceptionally welcoming toward the trio of elementary school girls who make up the Colors. She has a naturally affectionate and caring disposition, taking her responsibilities seriously without losing her gentle touch. Her primary motivation revolves around her future plans for the family business: she intends to inherit the bakery after finishing her schooling and convert it into an onigiri shop. This goal demonstrates her practical and entrepreneurial side, as well as her desire to bring her own vision to the family enterprise. Momoka’s role in the story is that of a kind and approachable older figure whom the Colors occasionally interact with. She offers them onigiri samples during the summer festival episode, and her cooking is well received. Her relationship with her younger sister Nonoka is defined by a typical sibling dynamic, with Nonoka sometimes teasingly warning the Colors about Momoka’s plans for the bakery. Despite being warm and reliable, Momoka has a notable quirk: she is utterly baffled by smartphones, highlighting a gentle disconnect from modern technology that contrasts with her otherwise capable demeanor. In terms of development, Momoka remains a steady presence throughout the series, embodying maturity and a sense of grounded responsibility within the community. She does not undergo major dramatic changes, but her consistent nature reinforces the everyday charm of the setting. Her notable abilities include cooking, particularly making onigiri, and managing household or business tasks with competence. Visually, she is depicted with long black hair and black eyes, often seen wearing a bright red-orange sweatshirt and a long black ruffled skirt, giving her a casual yet distinctive appearance.
